Gonzales v. Raich (2005)

Background

Angel Raich and Diane Monson were two California residents using cannabis medically under the state's Compassionate Use Act of 1996 (Proposition 215). Raich used cannabis for a brain tumor and other conditions; Monson grew her own plants for chronic pain. Both had physician recommendations and complied with California law ^[1].

In 2002, federal Drug Enforcement Administration agents raided Monson's home and destroyed her six cannabis plants, even though local sheriffs concluded she was within state law ^[1][2]. Raich and Monson sued Attorney General John Ashcroft (later replaced in the case caption by Alberto Gonzales), seeking an injunction against federal enforcement of the Controlled Substances Act (CSA) against patients using cannabis grown intrastate, non-commercially, for personal medical use.

The 9th Circuit ruled in their favor, holding the CSA likely exceeded congressional power as applied to this conduct ^[2]. The federal government appealed.

The legal question

The case turned on the Commerce Clause of the U.S. Constitution, which gives Congress power to regulate interstate commerce. The question was whether that power reaches cannabis that is:

• grown at home,
• never sold,
• never crosses state lines, and
• legal under state law.

Raich's lawyers argued this was purely local, non-economic activity outside federal reach — relying on recent cases like United States v. Lopez (1995) and United States v. Morrison (2000), which had narrowed Commerce Clause authority ^[3].

The ruling

On June 6, 2005, the Supreme Court ruled 6–3 against Raich. Justice John Paul Stevens, writing for the majority, held that Congress could regulate intrastate, non-commercial cannabis cultivation because, in aggregate, such activity could affect the interstate market for cannabis ^[3].

The majority relied heavily on Wickard v. Filburn (1942), the famous wheat-farming case where the Court held that a farmer growing wheat for his own use could be regulated because the cumulative effect of such activity affected interstate commerce ^[3]. Justice Antonin Scalia concurred separately, grounding his vote in the Necessary and Proper Clause ^[3].

Justice Sandra Day O'Connor dissented, joined by Chief Justice William Rehnquist and Justice Clarence Thomas. Thomas wrote a separate dissent arguing the majority's reasoning gave Congress "a perpetual license to ignore the Tenth Amendment" ^[3]. O'Connor — usually no friend of drug legalization — emphasized federalism: states should be allowed to serve as "laboratories" for policy experiments like medical cannabis ^[3].

The practical holding: the federal Controlled Substances Act applies everywhere in the United States, regardless of state law. Strong evidence

Why it still matters

Raich is the legal foundation for the federal/state cannabis conflict that persists in 2024. Key consequences:

• Federal illegality remains absolute. Even in fully legal states, cannabis is a Schedule I controlled substance under federal law. Raich confirms federal authority to enforce that, in theory, anywhere ^[4].
• Banking problems. Federally regulated banks generally refuse cannabis accounts because providing financial services to a federally illegal business creates money-laundering exposure. This is why so many dispensaries run on cash ^[5].
• Tax code 280E. Cannabis businesses can't deduct ordinary business expenses on federal taxes because they're trafficking in a Schedule I substance ^[5].
• No interstate commerce. States with legal markets can't ship cannabis to each other, even when both have legalized it.

What changed isn't the law — it's enforcement. The 2014 Rohrabacher–Farr amendment (renewed annually) bars the Justice Department from spending money to prosecute medical cannabis activity that complies with state law ^[6]. It does not repeal Raich; it just defunds enforcement against medical programs. Adult-use programs have no such protection and rely on prosecutorial discretion.

In 2024, the DEA proposed moving cannabis from Schedule I to Schedule III. That would soften some Raich consequences (notably 280E), but the underlying constitutional ruling — that Congress can regulate even homegrown cannabis — would remain ^[7]. Strong evidence

Aftermath for Raich personally

Angel Raich continued using cannabis after the ruling — there was never a federal prosecution against her — and pursued a follow-up case arguing a constitutional medical-necessity defense, which the 9th Circuit rejected in 2007 ^[8]. She remained a public advocate for medical cannabis access. The case stands as a reminder that winning a constitutional fight at the Supreme Court is hard even when the underlying conduct is sympathetic.
